我目前正在開發針對開源論壇軟件的修改。此修改允許用戶通過該論壇軟件進行捐贈。Paypal IPN問題 - 未處理一些付款
但是,最近用戶報告了可能由我的代碼引起的問題。我使用另一個開源庫來處理IPN連接 - An IPN Listener PHP class。
誰報告此問題已得到了以下電子郵件用戶:
你好
<My Name>
,請檢查您的服務器處理貝寶即時付款 通知(IPN)。發送到 以下網址即時付款通知是失敗:
http://www.MySite.com/donate/handler.php
如果不認識到這一點的網址,您可以使用所代表您使用IPN服務提供商 。請通過以上信息與您的服務提供商 聯繫。如果問題仍然存在,您的帳戶可能會禁用IP地址爲 。
感謝您對此問題的及時關注。
真誠的,貝寶
我擔心的問題來自於我的身邊,所以我要看看這一點,並確保。
我輕微修改了IPN Listener腳本,這導致我認爲我的修改導致了此問題。貝寶最近也有一些變化,可能會引發這個問題。
這是how類的樣子瞬間:

是否有任何問題與此腳本,這是造成這個問題?
P.S:URL donate/handler.php的確是IPN處理程序/偵聽器文件,所以它是一個公認的URL。
我沒有這個東西的工作,但它似乎不是你奇怪的是,*用戶*將獲得電子郵件。你確定地址配置正確嗎?貝寶是否不提供有關出錯的更多信息的日誌?他們應該。 –
對不起,我不明白:我發佈了這個修改和**用戶**是他自己的論壇的所有者,他是誰報告了這個問題。我沒有使用自己的修改,所以我不應該收到任何電子郵件。 – Aborted
